1st thing you need to establish is the actual engine temperature.
or is it a fault in the wiring.
or is it even overheating.
It is possible it is the thermostat but that takes me back to point 1.
My procedure with this would be plug in scan tool to read just exactly "what" temp the computer is "seeing"
while an independent thermometer measures the actual coolant temperature.
If my thermometer corresponds with the scan tool data temp and it is high then the thermostat is the next check.
Reason I'd go about this is French cars have bad wiring and can shot circuit across wires giving the computer crazy readings.
